浙江路桥大修工程的数字化实践与应用

随着数字化技术在桥梁工程中的快速发展，越来越多的桥梁在设计阶段和施工阶段都有深度运用，但是桥梁大修工程中的应用目前较少^1-2]。依托浙江路桥大修工程，详细介绍了文物铆钉钢桁架桥大修过程中的数字化应用，如三维模型参数化建立、方案三维动态模拟、三维激光点云扫描、手持式白光扫描等，为以后类似桥梁的修缮提供一定的数字化参考。

Digital Practice and Research of Road and Bridge Overhaul Engineering in Zhejiang

With the rapid development of digital technology in bridge engineering, the technology is applied deeply in the design stage and construction stage of bridges. But there are few applications in the bridge overhaul engineering. its application is less in at present. Relying on the road and bridge overhaul engineering in Zhejiang, the digital application in the overhaul process of cultural relic rivet steel truss bridge is introduced in detail, such as the 3D model parametric establishment, 3D dynamic simulation of scheme, 3D laser point cloud scanning and handheld white light scanning, which provides a certain digital reference for the maintenance of similar bridges in the future.
